Hello,
The way to go to manage python packages in DSS it to use code environments. You will be able to specify and install the pip packages you need.

Then going back to your notebook you will be able to change the kernel (Kernel>Change Kernel) to the one with the right code environment and therefore the needed packages.

I hope it helps,

Arnaud

I have created 3.6 evnironment. but yet when I check the python version it still shows 2.x

Hello,
Can you specify where you check the python version ?
If you are checking the version in a python dss notebook, have you changed the kernel before executing the cell ?
